Abstract: A discharge apparatus for discharging materials from a container onto a field, the apparatus comprising a power discharge device disposed adjacent to a discharge outlet defined by the container, the arrangement being such that when the apparatus is being used to spread the materials onto the field, the materials move from the container through the outlet towards the discharge device. A motor is drivingly connected to the discharge device for rotating the discharge device. A sensor senses the power used by the motor and a control controls the rate at which the materials are spread. A programmable device associated with the sensor and the control regulates the control. The arrangement is such that the programmable device dependent on the sensor regulates the control for controlling the rate at which the materials are discharged so that when the container is moved across the field, the materials are discharged onto the field at a varying rate in order to optimize usage of the materials.

Title: Truck traffic monitoring and warning systems and vehicle ramp advisory system
Inventor: BERGAN TERRY
IPC: G08G1/07
Filed: 1998-06-16
Abstract: Traffic monitoring and warning systems and vehicle ramp advisory systems are provided herein. Such system include at least one set of sensor arrays comprising a set of above-road electro-acoustic sensor arrays which are disposed above a traffic lane approaching a hazard for producing signals which are indicative of whether the vehicle is an automobile or a truck and, if it is a truck, to record the presence of such truck, and to provide signals which are indicative of the speed of such truck. A  processor is provided which has a memory for storing site-specific data related both to the geometry of the hazard and to signals which have been received from the at least one set of above-road sensor arrays. A traffic signalling device is associated with the traffic lane and is disposed downstream of the at least one set of sensor arrays, the traffic signalling device being controlled by the processor. The processor is responsive to the signals from the at least one set of sensor arrays for computing an actual speed of the truck and for computing a computed maximum safe speed for such truck at the hazard. The computed maximum speed of the truck is derived from the site-specific dimensional data of the hazard and from at least the initial speed of the truck, the computed maximum speed of the truck being a maximum speed for that truck safely to negotiate the hazard.  The processor compares the computed actual speed of the truck with the computed maximum safe speed for the truck. Then, the processor automatically operates the traffic signalling device if the computed actual speed of the truck exceeds the computed maximum safe speed for the truck. The processor also discontinues operating the traffic signalling device if the computed actual speed of the truck no longer exceeds the computed maximum safe speed for the truck.

Abstract: In an image-forming system, an image-forming substrate is used, which has a sheet of paper, and a layer of microcapsules coated over the sheet of paper.  The layer of microcapsules includes at least one type of microcapsules filled with an ink.  A shell wall of each microcapsule is formed of resin, which exhibits a temperature/pressure characteristic such that each of the microcapsules is squashed under a predetermined pressure when being heated to a predetermined temperature, thereby discharging the dye out of the shell wall.  A printer, having a roller platen and a thermal head, forms an image on the substrate.  The platen locally exerts the pressure on the microcapsule layer.  The tnermal head selectively heats a localized area of the microcapsule layer, on which the pressure is exerted by the platen, to a temperature in accordance with an image-information data, such that the microcapsules in the microcapsule layer are selectively squashed and an image on the microcapsule layer.

Abstract: A paper dryer section according to the present invention is useful in paper-making dryer apparatus having an increased rate of drying of a paper web compared with previous commercial apparatus, in a more compact papermaking dryer section. This is achieved through the use of a single tier of all top felted dryers, each of a larger than conventional diameter. In conjunction with top felting and air caps over the dryer rolls for the simultaneous drying of both sides of the web, the single tier arrangement in this invention prevents the formation of curl in the paper web being dried. Advantageously, the dryer section of the invention further employs air caps which are segmented in the cross machine direction to allow cross machine profiling of the temperature and quantity of air applied to the web, for uniform distribution of moisture content.
